Why do the words "Steve Jobs" and "programming" in the same sentence very slightly rub me the wrong way. Probably because one thing he wasn't, amongst all the superhuman things attributed to him by Apple zealots, is a programmer.
NeXTstep was all about revolutionizing the programming experience. For the time, it was dramatically more powerful and far easier than the completion. We are basically still using that app environment today ( on macOS and iOS ).
